[Cin] Timecode (ctrl + !)

[Igor BEGHETTO]

I think that "Timecode (Ctrl+!)" is documented enough, and you can find 
it in "Align Timecode".
See at 
https://cinelerra-gg.org/download/CinelerraGG_Manual/Align_Timecodes.html
or in the CinelerraGG_Manual_20220430.pdf, chapter 6.8.2 Align Timecodes 
(start from page 196 --> 216 of 736).
I haven't tried the shortcut yet but the feature worked good. See my old 
post https://lists.cinelerra-gg.org/pipermail/cin/2022-April/004935.html

Thanks!
